    I was somewhat surprised to find that if I harden a QVariant(bool) to the Windows Registry, and then read it back, the QVariant returned is a QVariant(string) with the value "false".

    Is that normal? Or have I messed up.

    Thanks
    David

      Windows Registry doesn't support bool type.
      So Qt would have to convert it to a supported type. I suppose toString() must be the simpliest.

        @Perdrix Can you show how you're writing/reading that value?
